iDetails on the permissible gross vehicle
weight of your vehicle can be found on the
vehicle identification plate ( Ypage 258).
It is better to have the vehicle transported
than to have it towed away.

evenly as possible. Excessive tractive
power could damage the vehicles.
If the drive wheels have become stuck in
loose or muddy ground, pull the vehicle out
with extreme caution, especially so if the vehi-
cle is loaded.
Never attempt to recover a stuck vehicle with
a trailer attached.
Pull out the vehicle backwards, if possible
using the tracks it made when it became
stuck.
Towing in the event of malfunctions

Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper-
age, the electric cables could be overloaded.
This could result in a fire. There is a risk of an accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
!Only use fuses that have been approved
for Mercedes-Benz vehicles and which
have the correct fuse rating for the system
concerned. Otherwise, components or sys-
tems could be damaged.
The fuses in your vehicle serve to close down faulty circuits. If a fuse blows, all the compo- nents on the circuit and their functions stop
operating.
Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed
in the fuse allocation chart.
iIf a fuse has blown, contact a breakdown
service or an authorized Mercedes-Benz
Center.
If a newly inserted fuse also blows, have the
cause traced and rectified at a qualified spe-
cialist workshop, e.g. an authorized
Mercedes-Benz Center.
Before changing a fuse
X Park the vehicle and apply the parking
brake.
X Switch off all electrical consumers.
X Remove the SmartKey from the ignition
lock.
All indicator lamps in the instrument cluster
must be off.
The fuses are located in various fuse boxes:
R Main fuse box on the driver's side of the
dashboard
R Fuse box in the front-passenger footwell
R Fuse box in the transmission tunnel
R Fuse box in the battery case
R Fuse box in the cargo compartment

pressures and correct them if necessary.
When parking your vehicle, make sure that
the tires do not get deformed by the curb or
other obstacles. If it is necessary to drive over
curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Oth-
